Seller represents and warrants to IQE (in the knowledge that IQE is entering into this Agreement in reliance on the accuracy of the warranties), as follows:

3.1 Organization and Good Standing. Seller is a corporation duly organized and validly existing under the laws of State of North Carolina. Seller has all requisite power and authority to own, operate and lease the Transferred Assets, to license to the Know How and the Licensed Software and to conduct the operations of the Business as presently conducted.

3.2 Authority. Seller has all requisite power and authority to execute and deliver this Agreement, the Supply Agreement, the Research and Development Agreement (as defined below) and the other documents, agreements, certificates and acknowledgments contemplated thereby (collectively, the “Transaction Documents”), and to perform the transactions contemplated hereby and thereby. The execution, delivery and performance of the Transaction Documents and the consummation of the transactions contemplated hereby and thereby have been duly and validly authorized by all necessary corporate action of the part of Seller. The Transaction Documents have been duly executed and delivered by Seller and constitute valid and binding obligations of Seller, enforceable against Seller in accordance with their respective terms, except that the enforceability thereof may be limited by bankruptcy, insolvency, reorganization or other similar laws affecting creditor’s rights generally and by principles of equity regarding the availability of remedies.

3.3 Effect of Agreement. The execution, delivery and performance of the Transaction Documents do not and will not: (a) conflict with the articles of incorporation or bylaws of Seller; (b) to the knowledge of Seller, violate any law or any rule or regulation of any governmental body or administrative agency, or conflict with any judicial or administrative judgment, order or decree relating to Seller or the Transferred Assets; (c) constitute a breach or default under any agreement or instrument by which Seller is bound or the Transferred Assets are affected; (d) create any Lien on any of the Transferred Assets; or (e) except as set forth on Schedule 3.3, require any consent, notice to or filing with any governmental authority, administrative agency or any other third party on behalf of Seller. The consents described on Schedule 3.3 are the “Required Consents.”

3.4 Title to and Condition of the Transferred Assets. Seller is the true and lawful owner of, and has good and valid title to the Transferred Assets, free and clear of any and all Liens other than (a) liens for taxes or other amounts not yet due and payable or (b) imperfections of title and encumbrances, if any, which in the aggregate are not material, do not materially detract from the marketability or value of the assets subject thereto and do not materially impair the operations of the owner or authorized user thereof (the “Permitted Liens”). Upon the consummation of the transactions contemplated in this Agreement at the Closing, IQE will acquire good and marketable title to the Transferred Assets, free and clear of all Liens other than the Permitted Liens.

3.5 Sufficiency of Assets. The Transferred Assets and the license of the Know How and the Licensed Software constitute all of the assets of any nature required to operate the Business in the manner presently operated by Seller, excluding only the Excluded Assets, and are sufficient to allow IQE to perform its obligations under the Supply Agreement.

3.6 Tangible Property; Inventory. Except as set forth in Schedule 3.6, all Tangible Personal Property is (a) in good operating order, condition and repair, ordinary wear and tear excepted, (b) suitable for immediate use in the ordinary course of business of the

Business, and (c) free from material defects. The Transferred Inventory was acquired in the ordinary course of business consistent with past practices and after taking into account any reserves or allowances is usable or saleable in the ordinary course of business.

3.7 Contracts. Each Assumed Contract and the Lease is the valid and binding obligation of the parties thereto, enforceable in accordance with its terms subject to equitable limitations. None of the Assumed Contracts requires a future payment or obligation assumed by IQE materially different than those made or performed by Seller in the ordinary course of business consistent with past practice. Subject to receipt of any Required Consents, Seller is not (with or without the lapse of time or the giving of notice, or both) in breach or default in any material respect of any Assumed Contract or the Lease and, to Seller’s knowledge, no other party to any of the Assumed Contracts or the Lease is (with or without the lapse of time or the giving of notice, or both) in breach or default in any material respect of any Assumed Contract or the Lease.

5.3 Employment and Benefit Plan Matters. The following provisions shall apply to certain employee-related matters:

(b) As of the Closing Date, the Transferred Employees who have an account balance in any defined contribution plan maintained by Seller shall be deemed fully vested in, and entitled to receive a distribution of, their entire account balances in accordance with the terms of such plans and shall be permitted to rollover his or her “eligible rollover distribution” (as defined under Section 402(c)(4) of the Code) to a qualified retirement plan established or maintained by IQE that contains a cash or deferred arrangement under Section 401(k) of Code. As of the Closing Date, the Transferred Employees shall cease to be eligible to make or receive contributions under any such plans of Seller (provided, however, that any contribution required to be made with respect to the participation of the Transferred Employees in such plans on or immediately prior to the Closing Date shall be made by Seller as soon as administratively feasible following the Closing Date, in accordance with Seller’s standard administrative practice for such plans).

(c) Effective as of the Closing Date, the Transferred Employees shall cease to be covered by Seller’s welfare benefit plans described on Schedule 5.3(c) (the

“Welfare Plans”). Seller shall retain responsibility in accordance with such Welfare Plan only for those claims incurred by the Transferred Employees (or their eligible dependents) under such Welfare Plans before the Effective Time. A medical or dental claim shall be deemed to be incurred on the date on which medical or other treatment or service was rendered (and not the date of inception of an illness or injury or the date on which a claim for treatment or service is submitted). A claim under the life and accident, disability insurance and severance pay plans shall be deemed to be incurred on the date of death, accident, injury or disability, or in the case of severance pay, the date the termination of employment giving rise to severance pay occurs. With respect to workers’ compensation injuries incurred by any Transferred Employees, (i) Seller shall retain responsibility for workers’ compensation claims filed by any Transferred Employee prior to the Effective Time or for services rendered by or acts or events occurring with respect to such Transferred Employee prior to the Effective Time, and (ii) IQE shall assume responsibility for claims resulting from an injury to or services rendered by or acts or events occurring with respect to such Transferred Employee after the Effective Time.

IQE shall be responsible for providing Continuation Coverage to Transferred Employees (and their eligible dependents) whose Qualifying Event occurs any time after the Effective Time.

(e) IQE shall use commercially reasonable efforts to provide the Transferred Employees with benefits that are, in the aggregate, substantially comparable to the benefits provided to them by Seller under the Welfare Plans immediately prior to Closing. For purposes of any employee benefits provided to Transferred Employees after the Closing Date, IQE shall credit (or cause to be credited) time of service accrued as an employee of Seller and its predecessors by such Transferred Employees as of the Closing Date for purposes of vesting, eligibility (but not for purposes of benefit accruals or the satisfaction of deductible or other monetary thresholds) and all pre-existing condition exclusions and actively-at-work requirements of such plans shall be waived for such employees and their covered dependents (other than limitations or waiting periods that are in effect prior to the Effective Time with respect to such employees and dependents that have not been satisfied). IQE shall recognize past service with Seller and its predecessors for all purposes for all of the Transferred Employees under the vacation and other benefit plans of IQE.

5.4 Confidentiality. In recognition of the confidential nature of certain of the information which will be provided to the parties, each party agrees to retain in confidence, and to require its respective directors, officers, employees, consultants, professional representatives and agents (collectively, its “Representatives”) to retain in confidence all confidential information transmitted or disclosed to it by the other party, and further agrees that it will not use for its own benefit and will not use or disclose to any third party, or permit the use or disclosure to any third party of, any confidential information obtained from or revealed by the other party, except that each party may disclose the information to those of its Representatives who need the information for the proper performance of their assigned duties with respect to the consummation of the transactions contemplated hereby. For the avoidance of doubt, the Know-How and the source code of the Licensed Software will be considered Seller’s confidential information and subject to the provisions of this Agreement relating to confidential information In making such information available to its Representatives, each party shall take any and all precautions necessary to ensure that its Representatives use the information only as permitted hereby. Notwithstanding anything to the contrary in the foregoing provisions, such information may be disclosed (a) where it is necessary to any regulatory authorities or governmental agencies; (b) if it is required by court order or decree or applicable law; (c) if it is ascertainable or obtained from public or published information; (d) if it is received from a third party not known to the recipient to be under an obligation to keep such information confidential; or (e) if the recipient can demonstrate that such information was in its possession prior to disclosure thereof in connection with this Agreement. If either party shall be required to make disclosure of any such information by operation of law, such party shall give the other party prior notice of the making of such disclosure and shall use all reasonable efforts to afford the other party an opportunity to contest the making of such disclosure; provided, however, if related to financial disclosure reporting obligations required by operation of law no such advance notice shall be required. In the event that the Closing shall not occur, each party shall immediately deliver, or cause to be delivered, to the other party (without retaining any copies thereof) any and all documents, statements or other written information obtained from such other party that contain confidential information of the other party.

(a) Seller shall prepare and timely file all tax returns required to be filed by Seller for any tax period ending on or prior to the Closing Date with respect to taxes for which Seller is responsible under this Agreement. Seller shall timely pay all taxes shown on any such tax return. Buyer shall prepare and timely file all tax returns required to be filed with respect to the Transferred Assets for any tax period or portion thereof beginning after the Closing Date (or for any tax period beginning before and ending after the Closing Date (a “Straddle Period”)). For purposes of this Section 5.5, in the case of any Straddle Period, the amount of any taxes based on or measured by income or receipts of Seller and the amount of any sales, use, employment or withholding taxes of Seller shall be allocated based on an interim closing of the books as of the close of business on the Closing Date, and the amount of other taxes of Seller for a Straddle Period that relate to the portion of such Straddle Period ending on the Closing Date shall be deemed to be the amount of such tax for the entire Straddle Period multiplied by a fraction, the numerator of which is the number of days in the portion of the Straddle Period ending on the Closing Date and the denominator of which is the number of days in such Straddle Period.

(b) After the Closing Date, each of IQE and Seller shall furnish or cause to be furnished to the other, upon request, as promptly as reasonably practicable, such information (including access to books, records and personnel) and assistance as is reasonably requested for the preparation and filing of any tax return or related document, for the preparation for any tax audit or for the prosecution or defense of any claim, suit or proceeding relating to liability for taxes of Seller or of IQE to the extent such taxes relate to the Transferred Assets.

8.1 Indemnification by Seller. Seller shall indemnify, defend and hold harmless IQE and its officers, directors and affiliates (the “IQE Indemnitees”) from, against, and with respect to any and all loss, damage, claim, obligation, liability, cost and expense (including, without limitation, reasonable attorneys’ fees and costs and expenses incurred in investigating, preparing, defending against or prosecuting any litigation, claim, proceeding or demand), of any kind or character (a “Loss”) arising out of or in connection with any of the following:

(a) any breach of any of the representations or warranties of Seller contained in this Agreement;

(b) any failure by Seller to perform or observe any covenant, agreement or condition to be performed or observed by it pursuant to this Agreement;

(d) Seller’s ownership and operation of the Business and the Transferred Assets prior to the Effective Time.

Notwithstanding anything herein to the contrary, each party acknowledges its duty to reasonably mitigate any Loss it might incur. Notwithstanding the foregoing, Seller will not have any responsibility or liability under this Agreement in connection with claims made by third parties under the warranty set forth in Section 3.13 to the extent they are directed at (i) modifications of the Licensed Software made by IQE or on its behalf, (ii) use or combination of the Licensed Software with materials, media, content, information or methods not provided by Seller under this Agreement, (iii) use of the Licensed Software in a manner not expressly authorized by this Agreement.

8.2 Indemnification by IQE. IQE shall indemnify, defend and hold harmless Seller and its officers, directors and affiliates (the “Seller Indemnitees”) from, against and with respect to any Loss arising out of or in connection with any of the following:

(a) any breach of any of the representations and warranties of IQE contained in this Agreement;

(b) any failure by IQE to perform or observe, any covenant, agreement or condition to be performed or observed by it pursuant to this Agreement;

(d) IQE’s ownership and operation of the Transferred Assets on and after the Effective Time.

8.3 Notice of Claim. Any party seeking to be indemnified hereunder (the “Indemnified Party”) shall, within thirty (30) days following discovery of the matters giving rise to a Loss, notify the party from whom indemnity is sought (the “Indemnity Obligor”) in writing of any claim for recovery, specifying in reasonable detail the nature of the Loss (so far as it is able) and the amount of the liability estimated to arise therefrom; provided a failure to provide notice within such 30-day period to the extent the Indemnity Obligor is not prejudiced by such delay. The Indemnified Party shall provide to the Indemnity Obligor as promptly as reasonably practicable thereafter all information and documentation reasonably requested by the Indemnity Obligor to verify the claim asserted.

8.4 Defense. If the facts pertaining to a Loss arise out of the claim of any third party, or if there is any claim against a third party available by virtue of the circumstances

of the Loss, the Indemnity Obligor may (subject to the Indemnified Party being indemnified and secured to its reasonable satisfaction in respect of all costs, charges and expenses reasonably and properly incurred by such party as a consequence of any actions taken at the request of the Indemnity Obligor pursuant to this Section 8.4), by giving written notice to the Indemnified Party within 30 days following its receipt of the notice of such claim, elect to assume the defense or the prosecution thereof, including the employment of counsel or accountants at its cost and expense; provided, however, that during the interim the Indemnified Party shall use commercially reasonable efforts (not including settlement) to protect against further damage or loss with respect to the Loss. The Indemnified Party shall have the right to employ counsel separate from counsel employed by the Indemnity Obligor in any such action and to participate therein, but the fees and expenses of such counsel shall be at the Indemnified Party’s own expense. Whether or not the Indemnity Obligor chooses so to defend or prosecute such claim, all the parties hereto shall cooperate in the defense or prosecution thereof. The Indemnity Obligor shall not be liable for any settlement of any such claim effected without its prior written consent (such consent not to be unreasonably withheld).

8.5 Third Parties. In the event of payment by the Indemnity Obligor to the Indemnified Party in connection with any Loss arising out of a third party claim, if an Indemnified Party subsequently becomes at any time entitled to recover from a third party (not being the Indemnified Party or its affiliates) any sum in respect of the matter giving rise to such Loss, the Indemnified Party shall take all necessary steps to enforce such recovery, and shall repay to the Indemnity Obligor as soon as reasonably practicable so much of the amount paid to the Indemnified Party as does not exceed the lesser of (i) the amount paid by the Indemnity Obligor in respect of such Loss, or (ii) the sum recovered from the third party (less all reasonable costs, charges and expenses incurred by the Indemnified Party in recovering that sum from such third party).

8.6 Time for Claims. Any claim asserted with respect to the items enumerated in Sections 8.1 or 8.2 must be submitted to the Indemnity Obligor in writing, or invoked in official proceedings, within twelve (12) months after the Closing Date, save in respect of Loss in relation to the representations and warranties in Sections 3.2, 3.3 3.4 and 3.9 (the “Fundamental Reps”), which must be submitted prior to the expiration of the applicable statutes of limitation. For the avoidance of doubt, in respect of a liability which is contingent or unascertained, the Seller shall not be required to invoke proceedings within the time limits set out in the set out in this Section 8.6 provided that written notice of the claim consistent with the requirements of Section 8.3 has been submitted to the Indemnity Obligor in accordance with this Section 8.6.

8.7 Limitation. Notwithstanding the provisions of Section 8.1, Seller shall not have any indemnification obligation under this Agreement unless and until the aggregate amount of the Losses of the IQE Indemnitees exceed $300,000 in the aggregate, whereupon Seller shall be liable to indemnify the Indemnified Party from and against all such Adverse Consequences in excess of such amount; provided, however, that this Section 8.7 shall not apply to breaches of the Fundamental Reps.

8.8 Maximum Indemnity Amount. In no event shall the aggregate amount for which Seller or IQE shall be liable as an Indemnity Obligor hereunder exceed $3,000,000; provided, however, that this Section 8.8 shall not apply to breaches of the Fundamental Reps.

8.9 Reduction by Insurance Proceeds. The amount payable by an Indemnity Obligor to an Indemnified Party with respect to a Loss shall be reduced by the amount of any insurance proceeds received by the Indemnified Party with respect to the Loss, and each of the parties hereby agrees to use its commercially reasonable efforts to collect any and all insurance proceeds to which it may be entitled in respect of any Loss.

8.10 Exclusive Remedy. Except for claims based on fraud or willful misrepresentation, the rights and remedies set forth in this Article VIII constitute the exclusive and sole rights and remedies of the parties in respect of the matters indemnified under this Article VIII; provided that this exclusive remedy for damages does not preclude a party from bringing an action for specific performance or other equitable remedy to require a party to perform its obligations under this Agreement. In no event will either party be liable to the other party for incidental, special, exemplary, punitive, or consequential damages of any kind.

9.1 Termination. This Agreement may be terminated at any time prior to the Closing:

(b) By Seller (if Seller is not then in breach of any term of this Agreement), if IQE shall (i) fail to perform in any material respect its agreements contained herein required to be performed on or prior to the Closing Date; or (ii) materially breach any of its representations or warranties contained herein, which failure or breach is not cured within ten days after Seller has notified IQE of its intent to terminate this Agreement pursuant to this subparagraph;

(c) By IQE (if IQE is not then in breach of any term of this Agreement), if Seller shall (i) fail to perform in any material respect its agreements contained herein required to be performed on or prior to the Closing Date; or (ii) materially breach any of its representations or warranties contained herein, which failure or breach is not cured within ten days after IQE has notified Seller of its intent to terminate this Agreement pursuant to this subparagraph;

(d) By either Seller or IQE, if there shall be any order, writ, injunction or decree of any court or governmental or regulatory agency binding on Seller or IQE which prohibits or restrains Seller or IQE from consummating the transactions contemplated hereby; or

(e) By either Seller or IQE, if the Closing has not occurred by July 31, 2012, for any reason other than delay or nonperformance of the party seeking such termination.

9.2 Effect on Obligations. Termination of this Agreement pursuant to this Article shall terminate all obligation of the parties hereunder, except for the obligations under Sections 10.4 (with respect to expenses) and 10.5 (with respect to publicity) and 5.4 (with respect to confidentiality); provided, however, that termination pursuant to subparagraphs (b) or (c) of Section 9.1 shall not relieve the defaulting or breaching party from any liability to the other party hereto.

10.1 Survival of Representations. Subject to the limitations on indemnification set forth in Section 8.6, all representations and warranties of the parties hereto contained in this Agreement or otherwise made in writing in connection with the transactions contemplated hereby shall survive the execution and delivery of this Agreement and the Closing.

10.2 Further Acts. From and after the Closing Date, upon the reasonable request of either party, the other party shall execute, acknowledge and deliver all such further acts, assignments, documents, agreements, acknowledgments, transfers, conveyances, powers of attorney and assurances as may reasonably be required or appropriate to carry out the transactions contemplated by this Agreement and to facilitate the transition of the Business from Seller to IQE, the assumption of the Assumed Liabilities by IQE and to address matters in a manner consistent with the express provisions, spirit and intent of this Agreement.

Such confidentiality terms will continue to apply pursuant to this Section 10.5 and Section 5.4 after the Closing Date.

Notwithstanding the foregoing, either party may make filings required by law upon prior written notice to the other party.
